“…[49] One can conclude that the 3D structure of metal NPs assembly greatly affects the conversion efficiency. What is more, the composites composed of multiple components also demonstrate outstanding performance, such as 3-dimensional rock wool decorated with ZIF-67@MXene/rGO, [50] MWCNT/ZrO 2 /Ni@CQDs coated on melamine foam surface. [51] In addition to the structures fabricated in labs, delicate architectures are broadly distributed all around the natural world, especially among butterflies and moth wings.…”

Effective solar steam generation is regarded as a prospective technology for seawater desalination and water purification, owing to its capability of solar light absorption and heat conversion. Numerous efforts have been dedicated to exploring photothermal materials with various delicate microstructures. However, investigations of the coupling effect of structure and component still need to be done. Herein, a superior solar steam generator of 3D bicontinuous interconnected gyroid‐structured Au materials (Au gyroid) by depositing Au nanoparticles onto C. rubi butterfly wings is reported. Au gyroid is proven to possess the evaporation rate and efficiency of 1.29 kg m−2 h−1 and 74.0%, under 1 sun irradiation. What is more, the evaporation rate and efficiency of lattice‐structured Au materials (Au lattice) as a comparison are 1.14 kg m−2 h−1 and 65.4%. The outstanding performance of Au gyroid is mainly ascribed to its 3D densely distributed hotspots and interconnected nanochannels, which are beneficial for strong broadband light absorption, sufficient water supply, as well as confinement effect for water heating. This work will provide insight into the future design and synthesis of novel plasmonic absorbers in photothermal conversion, photocatalysis, and photovoltaic devices.

“…Solar–thermal conversion materials are the core component in solar steam generators. The past decade has witnessed the development of novel solar–thermal materials for solar-driven evaporation applications, including noble metals, − carbon materials, − semiconducting materials, , and conjugated polymers. , Although these materials can deliver favorable absorption capability over the full solar spectrum and provide high light-to-heat efficiency for water evaporation, the structural design of evaporation systems is crucial for fully utilizing the solar absorption and solar–thermal conversion of the materials and approaching or exceeding theoretical evaporation performances. Compared to conventional two-dimensional (2D) solar-driven evaporators with planar configurations, three-dimensional (3D) solar evaporation systems are more effective in improving the solar steam generation performance.…”

Although significant advances have been achieved in developing solar-driven water evaporators for seawater desalination, there is still room for simultaneously enhancing water evaporation efficiency, salt resistance, and utilization of solar energy. Herein, for the first time, we demonstrate a highly efficient three-dimensional (3D) mirror-assisted and concave pyramid-shaped solar–thermal water evaporation system for high-yield and long-term desalination of seawater and brine water, which consists of a 3D concave pyramid-shaped solar–thermal architecture on the basis of polypyrrole-coated nonwoven fabrics (PCNFs), a 3D mirror array, a self-floating polystyrene foam layer, and a tail-like PCNF for upward transport of water. The 3D concave pyramid-shaped solar–thermal architecture enables multiple solar light reflections to absorb more solar energy, while the 3D mirror-assisted solar light enhancement design can activate the solar–thermal energy conversion of the back side of the concave pyramid-shaped PCNF architecture to improve the solar–thermal energy conversion efficiency. Crucially, selective accumulation of the precipitated salts on the back side of the concave pyramid-shaped architecture is realized, ensuring a favorable salt-resistant feature. The 3D mirror-assisted and concave pyramid-shaped solar-driven water evaporation system achieves a record high water evaporation rate of 4.75 kg m–2 h–1 under 1-sun irradiation only and exhibits long-term desalination stability even when evaporating high-salinity brine waters, demonstrating its great applicability and reliability for high-yield solar-driven desalination of seawater and high-salinity brine water.
